Once you do find drivers and install them, you should make sure you use the same physical USB connection each time. Sometimes the OS will ask you to re-install the drivers if you plug it into another spot. Actually, trying a different spot now may yield a surprise.. if it worked at one point in time. The drivers may be tied to a different physical port.

Don't know why, I've just seen it happen more than once.

I do not work here, but the benefits are still awesome
